a Th-is invention relates to improvements in.

p links and more 1 particularly to links of the 1 o split pivoted.typeobject of the" invention is to. provide "I an improved link. of. thegeneral type 'ref? istic 'ofthe invention resides in the specialconstruction and arrangement of means pro- 'vi di-ng for lockingthelinkmemberstogetheragainst lateral displacement. when the same H are in'closed relationship.

by a transverse pivot 4E for relative lateral out departing from thespirit of the invention.

Referring to a detailed description of the particular embodiment of theinvention illusparticularconstruction shown includes two similar membersA and B, each of said members comprising a body or shank portion I withhook portions 2 at the ends thereof and disposed in a common planetherewith. The body or shank portion 1 of the'members A,-B,.have roundedouter faces, the same being shown of elliptical form. The hook portions2 each have an inner section or butt portion 2 circular in cross sectionand of sfibstantially the same thickness as the body portion 1, and anouter section 2 reduced in thickness at its inner side and provided witha Hat inner side face 3, said outer sections being substantiallysemi-circular shape; in crosss'ect-ion, the same being shown split orreduced on their-inner sides oblique- .,,ly in the direction of theirouter ends, the said side face 3' of each hook portion 2 terminating atits outerv end portion in a slight -curve., and being correspondinglycurved" at its inner end "portion, as. shown. 7 The members A and B arepivotally con-- nected' side-by sideat their body portions 1 movement ofthe opposing hook portions 2.

' When' thepmembers A, B, are brought together, as shown in Figures 1and 2 of the drawings, each pair of opposing hook portions 1 cooperateto form a closed eye, the

outer reduced sections 2l of the hook portions fitting against eachother in overlapping relation. In Figure 3, the pairs of book portions2' are shownseparated or in open position. The body portions 1 of themembers A. and B' are provided at their inner sides with smooth, fiatbearing faces 5. The pivotv 4: preferably, as shown, takes the form ofav separate pin extending through suit able bearings 6 in the body orshank por tions 1 and'being beaded at its ends.

closed position, each hook portion 2 is provided with a shoulder portionor lug 7 and a recess 8 the arrangement beingsuch that when the hookportions 2 are brought to closed position, as illustrated in Figures 1and 2, the

shouldered portions or lugs 7 on the hook portions 2 of one of themembers A, B, enter the recesses 8 in the hookfportions2 of the otherlink member. The shoulder portion or lug and recess 8 of each hookportion 2 are located. at opposite sides thereof at'the end portions ofthe outer reduced sections 2'. The shoulder portion or lug 7 of eachhook 2 is formed continuous with the thicker inner'sece;

tion or butt portion 2*, said shoulder portion,

or lug extending forwardly from theoutenend ofthe butt portion 2 andprojecting outwardly from the inner flat side face f the outer section2". The shoulder portion 'or lug 7, which is disposed adjoining theinner edgeof the hookportion 2, has aninner fiat side face 9 and aforward beveled face 10.

The outer [face of the shoulder portion'or 7 lug 7 is roundedcorresponding with the adjoining rounded' outer face of the hookportion! The flat side face 9 of the shoulder portion or. lug 7 extendsat an abrupt angle to thepivotal aXis of the members A, B, the

same being shown extending at substantially right angles thereto. Eachof the recesses 8 y is formed, as shown, with a fiat side wall 11 to fitagainstthe side face 9 of the shoplder portion or lug 7, and with an endwall 12v curved or beveled to correspond to that of the lug 7.

7 forward face 10 ofthe shoulder portion or The special constructionofthe shoulder portions or lugs 7 and recesses 8 affordsefficient meansfor locking the hook'portions 2 together against lateral displacement.The particular constructlon' and arrangement avoids the necessity forrecessing'and weakening theouter reduced overlapping .p'ortions 2intermediate their ends: The locking shoulder portions or lugs 7 formedcontinuous with the thlcker inner sections or portions-2 of the hook 2provides a strong construction and the particular contour "and thelocation of the shoulder portions adjoining the outer ends of the innersections or butt portions 2 'is such as to avoid breakage by contactwith othenparts in the use'of the device, the resulting link structurebeing of a I strong, durable, satisfactory nature that can be producedat low cost, the link members A, B, being easily formed by casting.. 7

' In the modified construction illustrated in e 7 Figures 5 to 8 ofthedrawings,'the invention is shown applied to a snap hook. Theconstruction includes a body or shank 13 having at one end a snap 14 andprovided at its other end with a pivoted split link comprisinga" pair ofsimilar members 15, 16, said members having body or shank portionsdesignated respectively 17 18, withhook portions 19, 20, at one-endthereof. I The body or'shank portion 17, of themember 15, is formedintegral 2 V with the body or shank 13 of the snap device,

the body or shank portion 18 of the other member 16 beingpivotallyconnected by'a pin or rivet 21 to the body or shank portion 17.

The hook portions 19 and 20 of the respective'membersjl'5, '16, havein'nerf sections or. I e butt portlons and outerreduced sectlons, as.shown, said hookportlons being sim lar 1n form to the hookportions ofthe construction illustrated in Figures 1 to .tof the drawings,

and adapted when brought togetherto mate 7 are provided with shoulderportions'or lugs construction illustrated "in Figuresl to 4 of thedrawings, and cooperatlng n a similar manner to'lock the hook portions15and 16 I against'lateral displacement "when the same are in closedvposition as illustrated Fig- 1 ures 1 and 20f the drawings: l/VhatIclaim isz r '1.
